I can totally relate to what you're describing and I also think it's normal to feel that way. I never went out that much pre-injury, but the few times I've been invited to social events while dealing with this pcs I've politely declined for fear of making my symptoms worse. The thought of being in a room with lots of people talking just makes me dizzy.

Do you listen to music when exercising? Maybe you could make a new workout mix to help motivate you to get to the gym. I find that helps me look forward to a workout. Also, this probably sounds silly, but maybe get a new workout outfit. If I get a new exercise top, I'm always more excited to break it in at the gym. Just a couple suggestions.
